CWE-285

Summary

  o A vulnerability in the password change function of Cisco Prime
    Collaboration Provisioning could allow an authenticated, remote attacker to
    cause the system to become inoperable.

    The vulnerability is due to insufficient validation of a password change
    request. An attacker could exploit this vulnerability by changing a
    specific administrator account password. A successful exploit could allow
    the attacker to cause the affected device to become inoperable, resulting
    in a denial of service (DoS) condition.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.

Affected Products

  o Vulnerable Products

    This vulnerability affects Cisco Prime Collaboration Provisioning (PCP)
    Releases 12.2 and prior.

    Administrators can determine the current PCP release from the Cisco PCP
    GUI:

     1. Log in to Cisco PCP
     2. Click the settings icon near the top right of the screen
     3. Click About

    The release information is also displayed on the login screen.

    Products Confirmed Not Vulnerable

    Only products listed in the Vulnerable Products section of this advisory
    are known to be affected by this vulnerability.

Workarounds

  o There are no workarounds that address this vulnerability.

Fixed Software

  o Cisco has released free software updates that address the vulnerability
    described in this advisory. Customers may only install and expect support
    for software versions and feature sets for which they have purchased a
    license. By installing, downloading, accessing, or otherwise using such
    software upgrades, customers agree to follow the terms of the Cisco
    software license:
    https://www.cisco.com/c/en/us/products/end-user-license-agreement.html

    Additionally, customers may only download software for which they have a
    valid license, procured from Cisco directly, or through a Cisco authorized
    reseller or partner. In most cases this will be a maintenance upgrade to
    software that was previously purchased. Free security software updates do
    not entitle customers to a new software license, additional software
    feature sets, or major revision upgrades.

    When considering software upgrades, customers are advised to regularly
    consult the advisories for Cisco products, which are available from the
    Cisco Security Advisories and Alerts page, to determine exposure and a
    complete upgrade solution.

    In all cases, customers should ensure that the devices to be upgraded
    contain sufficient memory and confirm that current hardware and software
    configurations will continue to be supported properly by the new release.
    If the information is not clear, customers are advised to contact the Cisco
    Technical Assistance Center (TAC) or their contracted maintenance
    providers.

    Customers Without Service Contracts

    Customers who purchase directly from Cisco but do not hold a Cisco service
    contract and customers who make purchases through third-party vendors but
    are unsuccessful in obtaining fixed software through their point of sale
    should obtain upgrades by contacting the Cisco TAC:
    https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html

    Customers should have the product serial number available and be prepared
    to provide the URL of this advisory as evidence of entitlement to a free
    upgrade.

    Fixed Releases

    Cisco fixed this vulnerability in Cisco Prime Collaboration Provisioning
    Release 12.3.

    Customers can download Cisco Prime Collaboration Provisioning Software from
    the Software Center on Cisco.com by doing the following:

     1.  Click Browse all
     2. Navigate to Cloud and Systems Management > Collaboration and Unified
        Communications Management > Prime Collaboration > Prime Collaboration
        Provisioning 12.3

        Collaboration Provisioning 12.3 page
